Improved propeller



UNITED STATES PATENT GEEICE.

JACOB BUSSER, OF PHILADELPHIA, PENNSYLVANIA IMPROVED PROPELLER.

Specification forming part 0f Letters Patent No. 4F,97, dated `Tanuary 3, 1865.

To all whom yit may concern Be it known that I, JACOB BUSSER, of Philadelphia, in the county of Philadelphia, in the State ot Pennsylvania, have invented a new Method ot' Propelling Boats; and I do hereby declare that the following is a full, clear, and exact description of the same, reterence being had to the annexed drawings, making a part of this specicatiomin which- Figure 1 is a perspective view; Fig. 2, a longitudinal elevation; Fig. 3, an end elevation, and Fig. 4 a longitudinal elevation of the movable parts detached.

Like letters rei'er to like parts.

A A are guides; B I3, cross-ties holding the guides A A in place; C C, movable framey working in the guides A A; D D, cross-ties securing C C; C C has a shoulder or projection, either square or V-shaped, which works in the guides A A; E E, connecting-rods attached to the paddles F F and causing the same to work together; F F, paddles used in propelling, and G G, paddles brought into use when backing; L L, connecting-rods attached to the same; H H', stationary upright pieces with a slot, b b', in which the levers I I move. The lever I is used for throwing the paddles Ii F in or out of gear. The lever Iis used for like purpose in connection with the paddles G. 'lheh vers I I are held securely in position by the pins c c; K K are lixed stays or braces strengthening the paddles when in use; M M, connecting-rod attached to the engine; d d, pins holding the connecting-rods E and L in place. The red lines show theposition of the parts when the engine is reversed. In the drawings their position is shown when propelling torward.

The nature of my invention consists in providing a strong framework of iron or any l other suitable material, the same so made as easily to be let into a bed made to receive them, said bed being attached to and projecting from the sides of the vessel, all the working or4 propelling parts when in place being under water. This whole arrangement being intended to take the place of the wheel, having advantages which the wheel does not possess, a greater propelling power and au ventire freedom, when in action, from back water, the paddles being alternately elevated and depressed as the frame moves backward and forward in the guides A A. The paddles are self-acting, being raised and lowered when the engine is in motion, by the action ofthe water upon them.

do not conne myself to the exact number of paddles and their arrangement, as shown in the accompanying drawings, as the same may be varied to circumstan cesfor instance, there may be two sets of paddles on each side, with alternating motion, in which case there will be little, if any, loss ot' power; also, the paddles for backing might be placed on a line with those used for propelling forward, instead ot' above them, as shown in the drawings, all thesebein g merely alterations not in the least at'tecting the principles of construction.

What I claim as my invention, and desire to secure by Letters Patent, is-

rIhe arrangement of the guides, frame, pad'- dles, stays, and levers, the whole being art ranged to operate as herein set forth, and for purposes herein specified.

JACOB BUSSER.
